Pyroid Colloidal Graphite Dispersion
Pyroid is a synthetic colloidal graphite dispersion used for pyrolytic carbon coatings in semiconductor wafer processing. The high-purity graphite is in a semi-colloidal form, which qualifies it under tariff item 3801.20.00 as a colloidal or semi-colloidal graphite preparation. It is not a separate chemically defined compound and is not excluded by Chapter 38 notes.
